LightWare Optoelectronics www.lightware.co.za recently launched a “low cost laser range finder” for hobbyists and students called the SF02. This device uses the time-of-flight of a pulsed laser to measure up to 40m at 12 readings per second. It has an optical filter so it works in both indoor and outdoor situations.
Lots of people have contacted me about a simple Arduino sketch that connects to one or all of the available interfaces on the SF02. These interfaces include a serial port, an analog output and a digital alarm. A first draft of the sketch is attached. The picture below shows the test configuration:
